^aAfter the LTF-MB recovery protocol was performed, the numbers of Salmonella cells captured were semiquantitatively determined by colony counting on XLD agar. +, 1 to 10 colonies; ++, 10 to 100 colonies; +++, over 100 colonies; ×, no colonies.

^bCelery and alfalfa sprouts required an additional overnight enrichment in RVS broth.
